IMPROVED -CARBURETED-AIR LAMP.

Specification forming part of Letters Patent No. 73,900, dated January 28, 1868.

To all whom it may concern Beitknown that I, J.D. JENKINS, of Charlestown, in the county of Middlesex and State-ot' Massachusetts, have invented a Safety Vapor- Lamp; and I do hereby declare that the l'ollowing is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference Vmarked thereon.

The nature of my invention consists iu couiblning within the body of a lamp aquantity of material (that will readily absorbviiuid) saturated with naphtha, and also a fan-blower that will throw a steady blast of air through said saturated material.

I am aware that portable gas-'machines have been made in which air has been made to pass throughsaturated material; butinallsuchcases the air-propelling arrangement acted irregularly or intermittently, thus requiring some kind of pressure-regulator, which necessarily added in the bulk of the machine; but l do not think any one has yet been devised in which a blast isblown through by afan-wheel, and securing, as I do, a steady iiow ot' carbureted air lwithout the intervention ot' a pressure-reguallor.

To enable others skilled in the art to make and uselmy invention, I will proceed to'descrihe its construction and use, reference being had to the accompanyingdrawings and the letters of reference marked thereon.

In the drawings, Figure 1 represents a ver: tical section of my'improved lamp. Fig. 2 is a perspective view of the same.

A is a base containing the clock-uork G H and a small centrifugal fan-blower, I.

L L is a tube leading from the fan-blower up into the chamber C, opening in the lower part, soas to deliver the air (sent iu by the blower) into the saturated material M.

M is ya mass of cotton, tow, wool, asbestus, or other suitable material, saturated with naphtha or some kindred iuid, covered by a wiregauze diaphragm, N N.

E is a gas-cock, and D a burner, made in any of the usual forms for hydrocarbon-vapor burners.

F is a plug used for drawing oft any 'surplus Huid.

To prepare my lamp for burning I first fill it by removing the burner D and pouring in a sufcient quantity vof naphthatoj ust saturate the packing,r M. The surplus, it therehe any, is to be drawn o" through the plug F. The burner and plug is then replaced and the clockwork G H wound up. It' now the gas-cock E is opened, the fan-blower I will throw a current of air through, the saturated packing M, and thence, having become carbureted in its passage, it will pass through the burner D and then burn, giving a steady, beautiful light.'l

The advantages that I claim for my improved lamp are that, as it contains no fluid except that held by the packing, there can be no ex plosiou, and that I get a very superior light at a very low cost. v

Having thus described my invention, I will proceed to set forth my claim.

What I claim as my invention,and desire to secure by Letters Patent, is-

As a new article ot' manufacture, a lamp iu which the vapor for burning is produced by sending a current of air through a saturated packing, said current being impelled bya laublower, substantially as and for the purpose set forth.
